I was using the licensed/paid version of Jira for an ongoing project. The project has tasks assigned to everyone on the team.
I recently had to move to the free version to Jira and no longer have the team I had before. There are tasks assigned to people no longer on the team. The project configuration no longer includes those members.
However, the tasks that were assigned to them *in the past* remain assigned to them. How can I remove those members from the tasks without having to do so manually one task at a time?
